SPECIFICATION forming part of Letters Patent No. 657,483, datedSeptember 4, 1906.

Application filed September 2, 1896. Serial No. 604,662. (No model.) W

To all whom it may concern;

Be it known that I, ALONZO T. Cnoss, a citizen of the United States,residing atProvideuce, in the State of Rhode Island, have invented a newand useful Improvement I in Fountain-Pens, of which the following is aspecification.

My invention relates to that class of foun-' tain-pens in which awriting-pen is employed; and it consists in improved means for keepingthe pen in proper condition for use by making the parts readilyaccessible for cleaning, as hereinafter fully set forth.

In the accompanying drawings, Figure 1 represents the longitudinalsection of a fountain pen provided with my improvement, showing thefeedbarof the pen in its proper position for writing. Fig. 2 representsthe pen in a reversed position, with the feed-bar turned away from thepen, whereby access may be had to both the feed-bar and pen for wipingthe same... Fig. 3 represents a detail section taken at right angles tothat shown in Fig. 1. Fig. 4 shows the pen-section re: moved from theink-reservoir.

In the drawings, A represents the ink-reservoir, B the pen-section, andO the closingplug at the upper end of the ink-reservoir. The feed-bar ispermanently attached either to the plug C or to some portion oftheinkreservoir and preferably to the said plug, and in that case I preferto make the feed-bar D in two parts, consisting of the upper and lowerportions 0. and b, the projecting lower end of the feed-bar beingdeflected to contact with the nibs 0f the writing-pen E. Within the boreof the outer tube 0 of the pen-section B is placed the tube (1, forming,with the tube 0, an annular space e, adapted to receive the shank of thepen E to hold the same, and the feed-bar D is provided with a lateralenlargement f, which bearsloosely against the walls of the pen-sectionto preserve the proper relative position of the lower end of thefeed-bar. In writing the ink will be carried to the nibs of the pen bycapillary attraction, and the air the said feed-bar.

to take the place of the ink thus drawn from the ink-reservoir will passupward through the open bore of the pen-section, and the capillaryattraction of the under side of the deflected feed-bar and theatmospheric pressure will serve to prevent the ink from flowing out ofthe lower end of the point-section under When the pen is to be laid awayfor any length of time after use, by simply unscrewing the pen-sectionfor one-half a turn of the screw the feedebar will be turned away fromthe under side of the pen to the position shown in Fig. 2, in which boththe pen and feed-bar may be wiped clean and the drying of ink betweenthe feed-bar and pen be prevented. The pen will thus be kept inorder forimmediate use when next required, and in case the ink has become driedbetween the feed-bar and the pen the rubbing movement of .the penagainst the surface of the feed-bar, caused by the unscrewing of thepen-section from the ink-reservoir, will e fiectually clear the driedink from both. Upon the removal of the pensection for filling theink-reservoir, as shown in Fig. 4, ready access will be had to both theALONZO T. GROSS.
